| Abstract: | In this paper, the mechanisms of sensitized nano-sized titanium dioxide are introduced briefly at first, followed by the analysis of the principle for sensitizer selection from the aspect of energy band match principle. The recent research progress in the absorption spectra, its photoresponse in the visible light range and performance about the nano-sized titanium dioxide sensitized by various kinds of sensitizer is summarized. Finally, the application of sensitizer-sensitized titanium dioxide in the aspects of solar cells, photocatalytic aplication, photo-splitting water, et al, is briefly introduced. Also, the prospective for the researchment on the improvement of titanium dioxide photoresponse and applieatio of photocatalyst are discussed. |
